DSCP

The Differentiated Services Code Point (DSCP) prioritization scheme redefines the Type of Service (ToS) byte in the IP header by combining the first six bits into 64 possible combinations. This use of the TOS byte is still evolving, but it can be implemented now by G700 Media Gateways. A DSCP of 40 (101000) is suggested for the expedited forwarding of packets.
